Description
Technical field
The utility model belongs to geometric sense metering field, relates to a kind of endoporus contact measuring apparatus of the automatic measurement machine for detecting inner hole of workpiece size, circularity, cylindricity and equal error of beating.
Background technology
At present, at mechanic factory workers, the processing in parts hole and the status measured in total quality control are just becoming and are becoming more and more important.This is the rapid raising due to parts Excircle machining manufacturing accuracy on the one hand, makes to propose corresponding requirement to the processing in parts hole, and the measurement difficulty on the other hand due to parts hole is more much bigger than parts cylindrical measurement difficulty.Hole measuring instrument of the prior art mainly contains: dial bore gage, micrometer inside caliper, air-gauge and electronic plug gauge etc.These survey instruments generally can only measure the diameter dimension of endoporus, for circularity, cylindricity and the form and position tolerance such as to beat of endoporus, then cannot measure.These hole measuring instruments are not suitable for using on automatic measurement machine.
Although probes touch formula gauge head can use on automatic measurement machine.But need detection workpiece being carried out to multiple spot in use, the horizontal and vertical movement for automatic measurement machine has very high precision and status requirement, so except there is complex structure, outside the problem that manufacturing cost is high, also measuring accuracy problem to be considered.
In sum, in order to the diameter dimension of parts endoporus, circularity, cylindricity can be carried out and the contact sensing of the form and position tolerance such as to beat, to reach user demand, and reduce the manufacturing cost of automatic measurement machine simultaneously, develop a kind of endoporus contact measuring apparatus imperative.
Utility model content
Problem to be solved in the utility model is to provide a kind of compact conformation, the endoporus contact measuring apparatus that easy and simple to handle, measuring accuracy is high, accurately can measure the diameter of parts endoporus, circularity, cylindricity and beat.
For realizing as above object, the technical solution adopted in the utility model is: a kind of endoporus contact measuring apparatus, comprises guide pillar, lever, rotating shaft, backing pin, sliding sleeve, long push rod, door, spring, sensor holder, sensor, long sliding sleeve, short push rod, locating slot and lower locating slot radially cross distribution on guide pillar is provided with, two locating slots are non-cross, be symmetrically installed with by rotating shaft and spacing two levers of backing pin in upper locating slot and lower locating slot respectively, be arranged in guide pillar with the long push rod of the contact of lower locating slot two levers by sliding sleeve, be arranged in guide pillar with the short push rod of the contact of upper locating slot two levers by long sliding sleeve, the end face of long push rod and short push rod contacts with the contact of lever, sensor is fixed on guide pillar by sensor holder, the contact of sensor contacts with door end face.
Long push rod and short push rod top are provided with door, and spring fitting is between door and sensor holder.
The utility model has following superiority after adopting technique scheme: the utility model compact conformation, volume is little, easy installation and maintenance, measure data pass to industrial computer by pen-type sensor, through the calculating of Survey Software, can accurately measure the diameter dimension of tested parts endoporus, circularity, cylindricity and beat, precision is high, error is little, and Detection job is reliable and stable.
Accompanying drawing explanation
Fig. 1 is the lower probe part structural profile schematic diagram of a kind of endoporus of the utility model contact measuring apparatus.
Fig. 2 is the upper probe part structural profile schematic diagram of a kind of endoporus of the utility model contact measuring apparatus.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Fig. 1 ~ 2, a kind of endoporus contact measuring apparatus, guide pillar 1 is provided with locating slot B and lower locating slot A radially cross distribution, two locating slots are non-cross, be symmetrically installed with by two spacing levers 2 of rotating shaft 3 in upper locating slot B and lower locating slot A respectively, backing pin 4 limits the slewing area of lever 2, be arranged in guide pillar 1 with the long push rod 6 of the contact of lower locating slot A two levers 2 by sliding sleeve 5, be arranged in guide pillar 1 with the short push rod 12 of the contact of upper locating slot B two levers 2 by long sliding sleeve 11, door 7 is arranged on long push rod 6 and short push rod 12 top, spring 8 is arranged between door 7 and sensor holder 9, promoting door 7 makes the end face of long push rod 6 and short push rod 12 contact with the contact of lever 2 all the time, sensor 10 is fixed on guide pillar 1 by sensor holder 9, the contact of sensor 10 contacts with door 7 end face.
Its principle of work is: the elastic force pushing and pressing door 7 of spring 8, make long push rod 6 and the contact contact close contact on lower locating slot (A) two levers 2, short push rod 12 and the contact contact close contact on two levers 2 in upper locating slot (B), measure contact pitch and be in maximum rating all the time.When measuring endoporus, the measurement contact on lever 2, owing to being subject to the restriction of inner hole of workpiece and guide pillar 1, can only, with rotating shaft 3 for axis oscillating, by the contact contact on lever 2, drive long push rod 6 and short push rod 12 to rise or decline; Drive be arranged on long push rod 6 and the short door 7 on push rod 12 top also follow with the contact of sensor 10 together with rise or decline, the distance that the contact of sensor 10 rises or declines becomes electric signal and passes to industrial computer, through Survey Software calculating thus realize inner hole of workpiece size, circularity, cylindricity and the measurement of to beat etc.It should be added that, due to contact, both sides be equidistant to the rotary hole center of lever 2, when measuring contact and moving 1mm, contact contact also moves 1mm, after completing measurement, treat that workpiece leaves the measurement contact on not engagement lever 2, pushed against by spring 8 and lever 2 is resetted, to treat that measurement is next time surveyed.
The utility model compact conformation, volume is little, easy installation and maintenance, measure data pass to industrial computer by pen-type sensor, through the calculating of Survey Software, can accurately measure the diameter dimension of tested parts endoporus, circularity, cylindricity and beat, precision is high, error is little, and Detection job is reliable and stable.
